Abstract

A highly efficient luminaire (100). The luminaire includes a light source (310) that emits light. The emitted light is redirected by a light transform er having a curved circular reflective interior surface (130), the reflective interior surface reflecting the light in a predetermined pattern. A substantial amount of light being may be reflected close to an axis coincide nt with a radial line defining a radius of the circular reflective interior surface. Additionally, a substantial amount of light may be reflected in a pattern with low divergency or parallel with an axis of the light transforme r. The light is transmitted to the exterior of the luminaire by an optical wind ow (110).
